I'm not a TCP/IP networking expert, but I'm pretty certain that 10.x.x.x addresses are the very definition of a private non-routable Class A network. Which means the subnet mask should be 255.0.0.0.
255.255.255.0 is the mask for Class C networks, which for private networks are generally defined as 192.168.x.x.
The first big question is can you ping the server from another machine on your private network? (Assuming ICMP8 is not blocked by a software firewall). If you can't ping it, then something is wrong with your network configuration. Are you able to access the server at the specified IP address through other services, such as telnet, ssh, ftp? (assumes that some of those daemons are running on the server)
Can the server ping itself? Does it's ethernet interface even work? Can it ping other hosts on the network? Keep asking questions like this and sooner or later you'll have your answer.
